另外,toyota 用的储氢罐在wiki上是这么写的:

A Hydrogen tank (other names- cartridge or canister) is used for hydrogen storage.[1][2][3] The first type IV hydrogen tanks for compressed hydrogen at 700 bars (70 MPa; 10,000 psi) were demonstrated in 2001, the first fuel cell vehicles on the road with type IV tanks are the Toyota FCHV, Mercedes-Benz F-Cell and the GM HydroGen4.+ |& q3 `; W% R( @: w: r6 v

那么, type IV hydrogen tank 是个什么东西呢?

Composite tanks such as carbon fiber with a polymer liner (thermoplastic). See rotational molding and fibre-reinforced plastic.

从储氢罐到 fuel cell 的管道也可能都用得是这种材料。

看介绍,目前趋势是低压储氢系统,比如30bar, 440psi的系统。这样可以用type I 的罐子。从减轻死重的角度,会用铝罐。 ^" n" A- U" V% J5 e- p
